Sliding Board, Particularly a Ski

ABSTRACT

The invention relates to a sliding board, particularly a ski, comprising a sliding surface, an upper shell, optionally, a core, steel edges, an upper belt and lower belt, and comprising at least one interface element, which is joined to the sliding board body and which is provided for mounting at least one binding element on the top surface of the sliding board. The interface element(s) ( 10 ) is/are shaped onto lateral flanks ( 6 ) that extend along the longitudinal sides of the ski. These lateral flanks ( 6 ) have been bound in the sliding board construction during the production of the sliding board.

The invention relates to a sliding board, particularly a ski, with a running surface, an upper shell, optionally with a core, steel edges, an upper flange and a lower flange, and with at least one interface element connected to the sliding board body and intended for arranging at least one binding element on the upper side of the sliding board.

EP-A-1 161 972 discloses a sliding board with a profiled rail system which comprises at least one rail extending in the longitudinal direction of the sliding board, which is connected to the sliding board body by a peg connection or anchorage by means of at least one formed-on peg or part of a peg. The fastening of the profiled rails is performed on the finished sliding board and consequently just replaces the otherwise customary screw fastening. In order to provide a sliding board with an already premounted profiled rail system, it is therefore necessary to carry out fastening and mounting operations on the finished sliding board.

The invention is based on the object of providing a sliding board which does not have this disadvantage.

The set object is achieved according to the invention by the interface element or elements being formed on side pieces which run along the longitudinal sides of the ski, the side pieces having been incorporated in the construction of the sliding board during the production of the sliding board.

According to the invention, side pieces provided with interface elements are therefore incorporated in the construction of the sliding board during its production. This dispenses with the subsequent fastening operations, such as screwing-on operations. The production of the sliding board continues to be very simple and, in particular, the activities of arranging bindings and ski binding parts, are rationalized considerably.

In the case of a preferred configuration of the invention, the side pieces have been connected to prepreg layers or the like during the pressing operation. In particular, the core may be built up from a number of layers separated from one another by at least one prepreg layer and optionally covered at least on one side likewise with at least one further prepreg layer. The prepreg layers in the core connect the individual core layers to one another and can at the same time be used in an advantageous way for also incorporating the side pieces in the body of the sliding board or connecting them to the core.

In this connection, it is advantageous if the side pieces have anchoring elements which are in contact with the prepreg layers.

It is also advantageous in this respect to insert the anchoring elements in the core during the production of the sliding board in such a way that they come into contact with their upper side and/or underside with prepreg layers and can in this way be incorporated in the construction of the sliding board.

Further features, advantages and details of the invention are described in more detail on the basis of the drawing, which schematically represents an exemplary embodiment of the invention and in which:

FIG. 1 shows a cross section through an embodiment of a ski configured according to the invention and

FIG. 2 shows an oblique view of a ski configured according to the invention.

FIG. 1 shows a cross section through a ski 1, which has an upper shell 2, a core 3, a running surface 4, steel edges 5 and a lower flange 10 running between the latter. A further layer, an upper flange 8, is introduced between the core 3 and the upper shell 2. The further construction of the ski 1 may comprise additional layers (not represented) or intermediate layers of different materials.

As FIG. 2 also shows, the side pieces 6 of the ski 1 are specially configured, at least in that region or in those regions where a ski binding or a ski binding part is to be arranged. The side pieces 6 are preferably injection-molded parts consisting of plastic, on which there are formed guiding elements 11 profiled with a rail-like shape, which are seated on the upper shell 2 of the ski 1 and have attachment parts 11 a, which can be engaged over, for example by correspondingly bent edge regions of base plates or the like. In the case of the configuration shown, the attachment parts 11 a face in the direction of the center of the ski.

Also formed on the side pieces 6 are anchoring elements 6 a, facing in the direction of the center of the ski, by means of which the side pieces 6 are incorporated in the core 3. The core 3 is of a multilayered construction, at least in the region of the side pieces 6 provided with the guiding elements 11 profiled with a rail-like shape, and in the case of the configuration shown comprises four core layers 3 a, in particular made of wood, which are separated from one another by prepreg layers 7. The uppermost core layer 3 a is covered by a further prepreg layer 7; a prepreg layer 7 is preferably likewise introduced between the lower flange 10 and the core 3. Outside the regions where the guiding elements 11 a profiled with a rail-like shape are provided, the core 3 may be constructed in a conventional manner. The prepreg-layers 7 comprise in a known way a fabric, scrim or the like of fibers, preferably glass or aramid, embedded in a polymer material, for example epoxy resin or phenolic resin. The anchoring elements 6 a of the side pieces 6 are inserted and accommodated in recessed regions 9 of two core layers 3 a and are in contact with their upper side and underside here with one of the prepreg layers 7 in each case. In this way, the side pieces 6 are firmly incorporated in the initially liquefying and subsequently curing resin material of the prepreg layers 7 during the pressing operation of the ski 1, which is carried out in a mold while pressure and heat are supplied.

The two side pieces 6 may also have connecting parts, which pass through the ski in the transverse direction.

The invention has been described on the basis of a ski. It goes without saying that the invention may also be applied in the case of other sliding boards, for example snowboards.
